What
When one Claude agent (a teammate) sends a message to another, the text is wrapped in a teammate tag before delivery. Before wrapping, the text now goes through a cleaning step. If that step changes anything, a second cleaning step based on who sent the message runs again and again, up to 4 times, until the text stops changing. Previously the text was cleaned once.
Why
Cleaning repeatedly until nothing changes catches cases where one pass leaves behind something the next pass would have removed.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what the cleaning steps remove from a message.
